Skinny Berry Smoothie

My family loves smoothies – my kids would drink one everyday if I’d make it for them. I love them too, however, they can be really high in calories once you add juice and yogurt to the fruit.

I thought I’d see if I could skinny it down a bit, and I did – two ingredients, that’s all that is in these Skinny Berry Smoothies! To be fair, I’ll take any excuse to use my amazing Ninja Blender. I seriously love this thing – it’s a total workhorse and whips up a smoothie in seconds flat!

This drink is sweet, fruity and a little bit thick and fizzy. Overall it’s absolutely delicious and at only about 36 calories for a rather large glass, it’s totally guilt free!

How to Make Skinny Berry Smoothies

Making a smoothie is about as simple as it gets. Throw a few ingredients in a blender, blend until smooth, pour in a glass and drink. Boom. Super simple. How about a few tips to get you started?

  1. Always use frozen fruit. I don’t like to add extra water to my smoothies, and that includes ice. If you have fresh fruit on hand, lay some out on a tray or even a paper plate in the freezer for 30 minutes to an hour. Voila! Frozen fruit! Plus you get the slushy smoothie texture without extra water that takes away the flavor.
  2. If you are averse to using an artificially sweetened diet soda, you could substitute coconut water or coconut milk, and add some honey. It will increase the calories but not enough to make this drink a no-go.
  3. Feel free to customize the flavors in this berry smoothie. Any fruit would be delicious, from pineapple to mango to strawberries to bananas.

But isn’t Diet soda bad for you?

Most things you put into your bad are bad if you overdo it. Too much artificial sweetener is not good for you, however in moderation, like a small amount in this skinny berry smoothie, can be fine. If you are concerned about your intake of artificial sweetener though, you should consult your doctor first.

    Great change Kristin. I have never been a smoothie pusher bc they really are high calorie! Only those young gals can drink them (or kids) and not suffer the consequences! This will be so refreshing in the summer!

  12. Jenn says:

    My friend adds Diet Mountain Dew to hers (of course you wouldn’t do that for kids) and I thought it was a great idea. I had never heard of anyone doing that before, love the idea of Diet 7up!
